“…Glazier suggests that b varies between 2/3 and 1, representing the two extremes of idealised boundary constraints where metabolic rate either scales with surface area (2/3) or scales with mass or volume limits (1) (Glazier, 2010). The different body forms and varied anatomical, morphological and behavioural adaptations of the five echinoderm classes all determine the oxygen consumption capacities of different echinoderm species (Shick, 1983;Warnock and Liddell, 1985;Lawrence, 1987b;Patterson, 1992), so variation amongst the classes might be expected. Such variation was also found by Lawrence and Lane when they compared the means of a number of interspecific echinoderm scaling constants (Lawrence and Lane, 1982).…”

SUMMARYEchinoderms are important components of deep-sea communities because of their abundance and the fact that their activities contribute to carbon cycling. Estimating the echinoderm contribution to food webs and carbon cycling is important to our understanding of the functioning of the deep-sea environment and how this may alter in the future as climatic changes take place. Metabolic rate data from deep-sea echinoderm species are, however, scarce. To obtain such data from abyssal echinoderms, a novel in situ respirometer system, the benthic incubation chamber system (BICS), was deployed by remotely operated vehicle (ROV) at depths ranging from 2200 to 3600m. Oxygen consumption rates were obtained in situ from four species of abyssal echinoderm (Ophiuroidea and Holothuroidea). The design and operation of two versions of BICS are presented here, together with the in situ respirometry measurements. These results were then incorporated into a larger echinoderm metabolic rate data set, which included the metabolic rates of 84 echinoderm species from all five classes (Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea). The allometric scaling relationships between metabolic rate and body mass derived in this study for each echinoderm class were found to vary. Analysis of the data set indicated no change in echinoderm metabolic rate with depth (by class or phylum). The allometric scaling relationships presented here provide updated information for mass-dependent deep-sea echinoderm metabolic rate for use in ecosystem models, which will contribute to the study of both shallow water and deep-sea ecosystem functioning and biogeochemistry.Supplementary material available online at
